Research checked: 2026-11-05. Check linked official notices before travel.

Cascadia County Park lies where Soda Creek meets the South Santiam River in western Oregon. A short forest walk leads to Lower Soda Creek Falls. If you are stopping outside summer, plan around the west picnic area, which stays open year-round.

A waterfall trail and a riverside stop

The park offers two ways to stretch your legs after the drive. Follow Soda Creek uphill toward the falls, or walk by the South Santiam River under old Douglas-firs. Look for traces of the historic Santiam Wagon Road during your visit.

Fees, hours, and seasonal access

Stay clear of cold, fast water

Enjoy the river from the bank if the current is swift or the water is cold. Snowmelt can bring faster flows and debris. Oregon emergency officials advise wearing a life jacket for water recreation, even on warm days.

Keep dogs leashed on the falls trail

Dogs can accompany you on the Lower Soda Creek Falls Trail on a leash.

Check how your campsite is assigned
